Abstract Balloon refractory calcific coronary plaques remain a technical challenge. Stent underexpansion is known as a major cause of restenosis and thrombosis. We report a case of in‐stent restenosis 5 months after stent suboptimal implantation in a noncompliant calcific atherosclerotic plaque which could not be disrupted by repeated prolonged high‐pressure balloon inflations. High‐energy excimer laser use altered underlying lesion morphology, allowing full stent apposition. Advances in equipment and technique have allowed more frequent use of high energy excimer laser technology during percutaneous coronary angioplasty with very low rates of complications. Laser technology represents a useful tool to overcome resistant lesions during percutaneous coronary interventions. © 2008 Wiley‐Liss, Inc.
